PRINTING PRESS.

To all er /10m it may concern.

Be it known that I, Ln QUINNO RI-IOAIJES, a citizen of the United States, and a resident of Fremont, in the county of Sandusky and State of Ohio, have invented certain new and useful Improvements in Printing Presses, of which the following is a specification.

The present invention relates in general to inking mechanism for printing presses, and more particularly to an improved track and adjusting mechanism therefor especially adapted for use with printing presses of the platen type.

In certain types of printing presses, notably the Gordon type, inking rollers travel back and forth over the inking table or disk and the type form or bed at every cycle of the press thereby taking the ink from the inking table and transferring or applying it upon the type in the form. Such inking rollers are usually provided with rolls or trucks which run upon tracks. The inking rollers vary somewhat in diameter due to physical changes in the environment and due to wear and again a small form does not require as much pressure of the inking roller upon the face of the type to properly apply the ink as does a larger form. Consequently considerable difliculty has been experienced in having the roller properly apply or transfer the ink when the size of the inking rollers vary or when widely different forms are used.

One of the principal objects of the present invention is to provide improved tracks for the trucks or rolls of the inking rollers which are readily adjustable to compensate for wear or to adapt the inking mechanism to various sizes of forms and thereby overcome the difficulties heretofore encountered.

Another object is to provide an improved track which has capacity for all necessary adjustment and which affords a positive bearing for the trucks of the inking rollers in all positions thereof.

Another object is to provide an improved track of this character which is of simple and durable construction. reliable in operation and easy and'inexpensive to manufacture and which may be readily and aecurately adjusted by a simple manipulation of its controlling elements.

Other objects and advantages of the invention reside in certain novel features of construction, combination and arrangement Specification of Letters Patent.

of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming part of this specification, and in which:

Figure 1 is a side elevational view illustrating the track and its adjusting mechanism for showing a portion of the frame of: the press Figure 2 is a detailperspective view of the movable web of the adjusting mechanism;

Figure 3 is a detail perspective view of the supporting plate of the hanger; and

Figure 4 is a similar view of the foot plate of the support of the upper arm of the track.

Referring to the drawings wherein for the sake of illustration is shown the preferred embodiment of the invention the numeral 10 designates the frame of the press which is preferably of the bed-and-platen of Gordon type. The frame may be of any con-- vcntional construction and supports the usual inking table or disk (not shown) and the usual bed or form (not shown). Inking rollers designated at 11, are provided and as usual travel back and forth over the inking disk and table and the type at every cycle of the press thereby taking the ink from the inking table and transferring or applying it upon the type. These inking rollers are provided with trucks or rolls 12 which ride upon a track. designated genorally at 15. This track comprises a vertical arm or portion 16, a lower curved ann or portion 17. and an upper arm 18 which extends adjacent the inking table.

The upper arm 18 of the track has :1 depending lug 19 provided with a threaded bearing 20. An adjusting screw 21 has one end cooperatively engaged with the threaded bearing 20 and is itself adjustably supported on a foot plate 22 secured upon the end 23 of the fountain stand and a shoulder 24 provided adjacent the upper corner of the frame. The adjusting screw 21 is adjustably mounted in an elongated slot 25 provided in the foot plate '22 by means of its head 26 and lock nuts 27 The head engaging one side of the foot plate and the lock nuts operating against the opposite side thereof whereby the screw is secured in any position in which it may be adjusted along the foot plate. Adjusting mechanism is provided forthe vertical arm of the track and includes a stationary wedge member 30 formed upon the main frame including in clined surfaces 31 and 32 and a movable wedge member 35 interposed between the frame and the vertical arm of the track and including inclined surfaces 36 and 37 cooperatively engaged with the inclined surfaces 31 and 32 of the stationary wedge member. Both the stationary wedge member and the movable wedge member are combined, as shown in the drawings, and it is obvious that as the movable wedge memher is adjusted along the stationary wedge member the-track will be adjusted toward and away from the frame and consequently toward and away from the bed or form.

.A hanger, designated generally at 40 carries themovable wedge member 35 and it includes a hanger plate ll secured by means of bolt 42 to the upper corner of the frame 10. The projecting portion of the hanger plate is provided with an elongated slot 43 and a hanger boltd l extends through the slot and is adjustably secured therein by means of its head and a lock nut 45, the head engaging one sideof the hanger plate and the lock lug engaging the other side thereof. 7 The shank of the hanger bolt is threaded, as indicated at 46 and is operathrough similar openings 54 and 55 provided in the portion of the frame which constitutes the stationary wedge member, the free ends of the bolts being threaded and being engaged with lock nuts 58 and 59,

"I It is ebvicus that the spaces defined by the openings 56' and'5'? affordan easy accessto the lock nuts 58 and 59 and. permit of the use'ofa wrench orother suitable instrument.

' ItIis also apparent that the elongated openiings52 and 53, and 54 and 55 permit of the necessary movements of the bolts'incident to adjustment of the track.

adjustably'engaging in the threaded opening provided in the lower end of the arm 17 0f the track and its head is adaptedto'.

abut the adjacent portion'of the frame of the press.

1 Inop eration, when it is necessary tomake' an adjustment of thetracln lock nuts 58 and 59 are loosened and the lock nuts 27 are also'loosenedgj: The lock nut 45 is then'run' down on the threaded shank of the hanger bolt and the hanger bolt is turned to raise or lowerthe movable wedge member thus permitting the track to move toward the frame or force it to move away therefrom When the track has been ad- 7 'to compensate for the wear of the inking roller and for variations in its size, due to other conditions and also may be adjusted in order to obtain the proper pressure of the roller upon the face of the type when the forms vary incharacter or in size;
